Black-and-white spotted lanternfly nymphs about a quarter-inch long are starting to hatch in the region. If you haven’t seen them in your yard yet, it could only be a matter of time.
Black-and-white spotted lanternfly nymphs about a quarter-inch long are starting to hatch in the region, hopping across decks, patios, and trees before they morph over the summer into flying Technicolor adults.The invasive pests are turning out to be pretty mobile, either through hopping, flying, or hitching rides, according to a recent study in which Pennsylvania served as ground zero.
She and her coauthors sought to measure the annual movement of the insect, either on its own or by hitching rides on cars, trains or anything that moves. The team analyzed known locations of spotted lanternfly from 2014 to 2020, starting with Berks County. They pulled from 241,366 survey locations. It’s fast enough, coincidentally, that spotted lanternflies are now present in Indiana. And it helps account for how the pest has spread from Berks County to nine states altogether.
Spotted lanternflies also can spread rapidly because they will lay eggs almost anywhere and feed on up to 70 species of plants.Brian Walsh, a spotted lanternfly expert at Penn State, was out in the field this week counting spotted lanternfly instars, the newly hatched bugs.
